A man came to Ibrahim ibn Adam and said, “Advise me!” Ibrahim replied: I advise you with five things:1. If people busy themselves with worldly matters, busy yourself with next-worldly matters.2. If people busy themselves with beautifying their outward, busy yourself with beautifying your inward3. If people busy themselves with building palaces, busy yourself with preparing for your grave.4. If people busy themselves with others’ faults, busy yourself with your own faults5. If people busy themselves with serving created things, busy yourself with serving the Creator.
